VALID 141730Z - 141900Z
PROBABILITY OF WATCH ISSUANCE...20 PERCENT
SUMMARY...A THREAT FOR ISOLATED STRONG WIND GUSTS AND SMALL HAIL
WILL ACCOMPANY DEVELOPING TSTMS ACROSS PARTS OF SC AND SRN NC THIS
AFTERNOON. A WW IS NOT EXPECTED.
DISCUSSION...A SLOW-MOVING COLD FRONT IS EXPECTED TO STALL JUST N OF
THE NC-SC BORDER THIS AFTERNOON. RELATIVELY RICHER MOISTURE
POSITIONED TO THE W /PER 12Z SOUNDINGS/ IS SPREADING EWD ACROSS THE
CAROLINAS...ALONG THE NRN PERIPHERY OF A MIDLEVEL ANTICYCLONE
CENTERED OFF THE FL ATLANTIC COAST. WITH SFC TEMPERATURES ALREADY IN
THE UPPER 80S TO LOWER 90S F...AND MLCAPE VALUES APPROACHING 2500
J/KG...TSTM COVERAGE WILL INCREASE OVER THE NEXT COUPLE HRS ALONG/S
OF THE STALLING FRONT. MODEST WLY FLOW ALOFT /I.E. AROUND 20 KT AT
500 MB/ WILL SUPPORT A FEW WEAKLY ORGANIZED MULTICELL
